because there never was a forced parity thing, people just make stuff up and run with it for hits/attention/arguments

+Google for older evidence.

This is regarding arcade/indie/etc content, and when they say parity, they say content, as in they wont publish titles that have exclusive content on psn.

parity on content is not parity on resolution of graphical capability.
